Can't parse all messages from mbox

Hello everyone,

I have an issue about parsing an mbox file in autopsy. Autopsy can not parse all the messages in an mbox file. I’ve tested my mbox file (920 MB) with mboxviewer and it parsed all the messages consisting 6.321 messages. Meanwhile, when I used the autopsy, it could not parse all the messages as it just showed 221 messages.

is anyone have similar issue with this? is there any way how to solve it?
